How often should I change the oil in a heavy-duty truck?

Most diesel trucks require an oil change every 15,000 to 25,000 kilometres, depending on load, driving conditions, and engine hours. Sticking to this schedule helps reduce wear and maintain warranty compliance.

What fluids should be regularly checked in a diesel truck?

Key fluids include engine oil, coolant, transmission fluid, brake fluid, power steering fluid, and differential oil. Regular inspection and replacement are critical for extending component life and preventing system failure.
